Abstract:

This report covers work to develop a remote sensing method based on airborne gravity to determine bathymetry under ice covered oceans for mapping economic and military critical regions of the Arctic Ocean. An iterative forward modeling technique to modify initial admittance function based estimates of bathymetry from airborne gravity measurements to incorporate a sediment layer has been developed and evaluated Possible future improvements are discussed.
